In search of the most active MN4 catalyst for the oxygen reduction reaction. The case of perfluorinated Fe phthalocyanine
(ROYAL SOC CHEMISTRY, 2019)Iron macrocyclic complexes (MN4) are promising catalysts for replacing platinum (the industrial standard) in electrocatalysis. In particular, FeN4 complexes have shown lower overpotential than Pt for the oxygen reduction ... -
Differential source-sink manipulation affects leaf carbohydrate and photosynthesis of early- and late-harvest nectarine varieties
(BRAZILIAN SOC PLANT PHYSIOLOGY, 2019)Source-sink balance is a major determinant of carbon partitioning within plants. Thinning is an agronomic practice that consists of changing the ratio between leaves and fruits, the source and sink plant organs, respectively. ... -
Comparison of total hip arthroplasty surgical approaches by Statistical Parametric Mapping
(ELSEVIER SCI LTD, 2019)Background: The most common surgical approaches in use for total hip arthroplasty are the lateral and posterior. When comparing these approaches in terms of gait biomechanics, studies usually rely on pre-defined discrete ... -

Amazonian trees show increased edge effects due to Atlantic Ocean warming and northward displacement of the Intertropical Convergence Zone since 1980
(ELSEVIER, 2019)Recent investigations indicate a warming of Atlantic Ocean surface waters since 1980, probably influenced by anthropic actions, inducing rainfall intensification mainly during the rainy season and slight reductions during ... -
Opposing action of NCoR1 and PGC-1 alpha in mitochondrial redox homeostasis
(ELSEVIER SCIENCE INC, 2019)The ability to respond to fluctuations of reactive oxygen species (ROS) within the cell is a central aspect of mammalian physiology. This dynamic process depends on the coordinated action of transcriptional factors to ... -
Polyphenols obtained from Didymosphenia geminata (Lyngbye) Schmith altered the viability and proliferation of salmonids cells lines SHK-1 and CHSE-214
(ELSEVIER SCIENCE BV, 2019)Didymosphenia geminata (Lyngbye) Schmidt, also referred to as Didymo, is an invasive diatom that forms nuisance mats. Since it was first reported in our country in approximately 2010, Didymo has expanded and colonized ... -
Sex differences in nonmedical prescription tranquilizer and stimulant use trends among secondary school students in Argentina, Chile, and Uruguay
(ELSEVIER IRELAND LTD, 2019)Background Little is known about recent nonmedical prescription tranquilizer and stimulant use trends in Latin America. We tested whether recent trends among students in three South American countries differed by sex over ... -
Psychometric properties of the Spanish version of the Edinburgh Handedness Inventory in a sample of Chilean undergraduates
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2019)An individual's nervous and cognitive systems are lateralized, and handedness represents a behavioral manifestation of such organization. Therefore, accurately and reliably measuring handedness has repercussion on our ... -
A multiple-class distance-decaying approach for mapping temperature reduction ecosystem services provided by urban vegetation in Santiago de Chile
(ELSEVIER SCIENCE BV, 2019)Mapping ecosystem services is a challenging task, particularly for regulating services presenting spatial mismatches between the areas providing the services and those benefiting from them, such as the temperature reduction ... -
